available on firmwares 3.15 and earlier. Caveats: Support for the internal SATA controller is currently missing, as is support for framebuffer resolutions other than 720x480. These deficiencies will be remedied soon. Special thanks to Peter Grehan for providing the hardware that made this port possible, and thanks to Geoff Levand of Sony Computer Entertainment for advice on the LV1 hypervisor.
